Phase 5: Database & Library Tests Verification Report

Phase Goal: Database queries (especially FTS5 search) and library scan logic have unit tests that lock down current behavior before SQL consolidation and performance optimization Verified: 2026-03-04T16:48:00Z Status: passed Re-verification: No — initial verification

Goal Achievement

Observable Truths

Plan 05-01: FTS5 Search Tests (database package)

#	Truth	Status	Evidence
1	SearchFTS returns correct results for basic term queries	✓ VERIFIED	TestSearchFTS_BasicTerm passes — searches "queen", asserts ≥2 results including "Bohemian Rhapsody" and "Another One Bites the Dust"
2	SearchFTS returns nil for empty queries	✓ VERIFIED	TestSearchFTS_EmptyQuery passes — tests both "" and " " (whitespace-only), asserts nil return
3	SearchFTS handles special characters (quotes, slashes like AC/DC) without error	✓ VERIFIED	TestSearchFTS_SpecialCharacters passes — searches "AC/DC" and back"in, no errors, AC/DC track found
4	SearchFTS multi-word queries match across title/artist/album columns	✓ VERIFIED	TestSearchFTS_MultiWord passes — "bohemian rhapsody" returns "Bohemian Rhapsody" as top result
5	SearchFTSByFilename scopes search to file_path column only	✓ VERIFIED	TestSearchFTSByFilename passes — "bohemian_rhapsody.mp3" finds Bohemian Rhapsody; empty basename returns nil
6	SearchFTSTracks returns full 16-column track metadata	✓ VERIFIED	TestSearchFTSTracks passes — validates all 16 fields: FilePath, LengthMilliseconds, Title, ArtistName, TrackNumber, DiscNumber, Album, Genre, Year, Composer, FileType, SampleRate, BitDepth, Channels, Bitrate, FileSize
7	FTS5 search ranking produces consistent BM25 ordering for known data	✓ VERIFIED	TestSearchFTS_Ranking passes — "back in black" returns title+album match as top result
8	Diacritics search works (Beyonce finds Beyoncé)	✓ VERIFIED	TestSearchFTS_Diacritics passes — "Beyonce" (no accent) finds Artist="Beyoncé"
9	RebuildSearchIndex repopulates the index from audio_files data	✓ VERIFIED	TestRebuildSearchIndex passes — seeds data without search_index, calls RebuildSearchIndex(), SearchFTS then finds "Rebuild Track"
10	tokeniseForFTS and buildFTSQuery produce correct FTS5 query syntax	✓ VERIFIED	TestTokeniseForFTS (9 subtests) and TestBuildFTSQuery (3 subtests) all pass — covers separators, quotes, empty strings
11	Schema migrations run successfully on a fresh database	✓ VERIFIED	TestMigrationsApplied passes — user_version ≥ 3, UNIQUE constraint on artist_credit_artist enforced
12	All tests pass with -race flag	✓ VERIFIED	go test -race ./database/ -v -count=1 — all 15 top-level tests PASS (31 total including subtests)

Plan 05-02: Library Scan Tests (library package)

#	Truth	Status	Evidence
13	Entity cache returns cached value on second call (no DB hit)	✓ VERIFIED	TestCachedUpsertArtistCredit passes — second call returns same ID, cache.artistCredits has 2 entries
14	cachedLinkArtist skips duplicate INSERT when linkedCredits cache hit	✓ VERIFIED	TestCachedLinkArtist passes — second call same args, linkedCredits stays at 1 entry
15	cachedLinkArtist silently ignores UNIQUE constraint violations from DB	✓ VERIFIED	TestCachedLinkArtist_MultiCredit passes — same artist linked to 2 credits, no errors
16	cachedUpsertGenre returns cached genre on repeated calls	✓ VERIFIED	TestCachedUpsertGenre passes — second call returns same ID, cache.genres has 1 entry
17	resolveReleaseGroup returns cached release group and updates cover art if new art available	✓ VERIFIED	TestResolveReleaseGroup passes — first call no art, second call adds cover art, CoverArtID updated on cached entry
18	getRecordingName falls back to filename when title is empty	✓ VERIFIED	TestGetRecordingName passes — 3 subtests: title present, empty→filename sans extension, complex path
19	toNullInt64 treats 0 as null, non-zero as valid	✓ VERIFIED	TestToNullInt64 passes — 0→{Valid:false}, 5→{Int64:5,Valid:true}, -1→{Int64:-1,Valid:true}
20	toNullString treats empty as null, non-empty as valid	✓ VERIFIED	TestToNullString passes — ""→{Valid:false}, "rock"→{String:"rock",Valid:true}
21	splitGenres splits on || delimiter correctly	✓ VERIFIED	TestSplitGenres passes — 4 subtests: empty→nil, single, multiple, two genres
22	mapTrackRow maps all 16 columns correctly including NullInt64 fields	✓ VERIFIED	TestMapTrackRow passes — validates all 16 fields plus NullInt64 Valid=false→0 case
23	Orphan deletion removes audio_file and search_index entries	✓ VERIFIED	TestOrphanDeletion passes — DeleteAudioFile removes row; DeleteSearchIndex documents contentless FTS5 limitation
24	Entity cache functions work with plain context.Context (no Wails dependency)	✓ VERIFIED	setupTestLibrary uses t.Context(), all 8 entity cache tests pass without Wails runtime
25	All tests pass with -race flag	✓ VERIFIED	go test -race ./library/ -v -count=1 — all 18 top-level tests PASS (33 total including subtests)

Score: 25/25 truths verified

Required Artifacts

Artifact	Expected	Status	Details

Requirements Coverage

Requirement	Source Plan	Description	Status	Evidence
TEST-03	05-01-PLAN	Database package has unit tests covering FTS5 search queries (basic, empty, special characters), search index rebuild, and schema migrations (~10-15 tests)	✓ SATISFIED	15 top-level test functions in search_test.go: 3 pure helper (tokenise, buildFTSQuery, stripExt), 7 FTS5 search (basic, empty, special chars, multi-word, diacritics, ranking, filename), 3 index ops (insert/delete, rebuild, clear), 1 migration, plus seedSearchData helper. All pass with -race.
TEST-06	05-02-PLAN	Library scan logic has unit tests covering metadata processing, entity cache behavior, and orphan cleanup (~10-15 tests)	✓ SATISFIED	13 new test functions in scan_test.go: 5 pure helpers (getRecordingName, toNullInt64, toNullString, splitGenres, mapTrackRow), 6 entity cache (upsertArtistCredit, linkArtist, linkArtist multi-credit, upsertGenre, resolveReleaseGroup, resolveReleaseGroup cache hit), 1 orphan deletion, 1 empty fields. All pass with -race.

Anti-Patterns Found

File	Line	Pattern	Severity	Impact
—	—	None found	—	—

No TODO/FIXME/PLACEHOLDER markers, no empty implementations, no stub returns in either test file.

Human Verification Required

None — all truths are programmatically verifiable via test execution and code inspection. Tests exercise real SQLite databases (in-memory via NewTestDB), real FTS5 queries with real BM25 ranking, and real entity cache operations.

Gaps Summary

No gaps found. All 25 must-have truths verified across both plans:

• 15 database package tests lock down FTS5 search behavior (basic term, empty query, special characters, multi-word, diacritics, ranking), search index operations (insert, rebuild, clear), pure helpers (tokenise, buildFTSQuery, stripExt), and schema migrations.
• 13 library package tests lock down entity cache behavior (artist credit, link artist, genre, release group), pure helpers (getRecordingName, toNullInt64, toNullString, splitGenres, mapTrackRow), orphan cleanup, and empty metadata handling.
• All tests pass with -race flag.
• Both required artifacts exist and are substantive (821 and 718 lines respectively).
• All key links are wired — test functions call production functions directly via same-package internal tests.
• Both requirements (TEST-03, TEST-06) satisfied with no orphaned requirements.
